Radu Rendec 64d2f4594e gpio: pcf857x: Implement get_multiple/set_multiple methods
This change allows the GPIO core to read/change multiple pins in a
single driver call and subsequent I2C transfer. It helps a lot with
PCF857x devices, since their I2C protocol always reads/changes all
existing pins anyway. Therefore, when the GPIO client code does a bulk
operation on multiple pins, the driver makes a single I2C transfer.
